COFFEE OR SPICE MILL.

Application led January 22, 1909.

To @ZZ whom it may concern:

Be it known that ALONZO A. VARNER, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful improvements in Coffeeor Spice Milla of which the following is a specification.

My invention relates to improvements in coffee or spice mills, and theobjects of my improvements are simplicity and economy in constructionand convenience and efficiency in use.

In the accompanying drawing: Figure 1 is a side elevation of my coffeeor spice mill. Fig. lllis a horizontal section of the bracket arm online s s Fig. 1. Fig. Q, is an enlarged vertical section of portions ofmy mill on the line a a Fig. 4, with portion of hopper broken away,adjusting mechanism and crank omitted, and forcer and runner in sideelevation. Fig. 3 is a plan view of the clamp ring for my mill. Fig. lis a rear eleA vation, part broken away and base of hopper and clampring in section. Fig. 5 is a sectional view on the line a: Fig. a, ofportions of the case or body of my mill. Fig. is a sectional view of thesame on y/ y of Fig. il. Fig. 7 is a front elevation of the window bosson the hopper and integral window lugs before being bent into' theirlinal forni. Fig. 8 is an enlarged sectional view on the line .e e',Fig. 1, of the same with the lugs bent into form to receive the windowpane together with a sectional view of the said pane. Fig 9, is a likeview of the same, with the lugs bent into their final form.

rlhe case or body of the mill is a two part structure, consisting of themain or wall part 10 and front or cap 11, the said wall part having abracket arm 12 and wall plate 18 for securing the mill to a wall. Thesaid two parts are provided with interlocking lugs and recesses belowthe upper end, while at the said upper end the parts are provided eachwith a semi-cylindrical and hollow neck, the two forming interiorly themouth of the case at the base of a separate hopper 111 and exteriorly acylindrical neck 15 to receive the cylindrical lower end 1G of thehopper 14. The case in general is or may be of any ordinary form, theonly feature thereof which is essential to my invention being thecylindrical neck at the upper end of its two parts.

Specification of Letters Patent.

Serial No. 473,612.

rIhe case is fitted in any ordinary way to the shaft 1T, carrying amoving mill disk or runner 18 and screw or worm 19, a crank 20, and anydesired adjusting devices, as at 21. A. fixed -mill disk 22 surroundsthe screw or worm 19 and is held in any proper manner within the case toact in opposition to the moving disk 18. I

As shown, the lugs and recesses comprise guide lugs 23 on the front 11which engage with the rim of the wall part 10, as shown best in Fig. 6,to secure proper registration of said front and wall part, and a lug 24mounted on a iange 25 extending outwardly from the front 11 engagingsuitable flanges 26, extending outwardly from the wall part 10, as bestshown in Fig. 5, for locking said front 11 and wall part 10 together.

The moving mill disk 18 has a backwardly extending hub 27 at its center,suitably for mounting on the shaft 17 and is provided with a clearer orwiper consisting of a rib 28, extending from said hub 27 in a generallyspiral line to the outer edge or rim of said disk 18, the top edge Ofsaid rib 28 substantially fitting the inner wall of the wall part 10,said rib 28 being adapted when said moving mill disk 18 is operatedrotatively on its axis to sweep through and over the interior spacebetween the said inner wall of the wall part 10 and the general surfaceof the back wall of said moving mill disk 18 and thereby prevent theaccumulation of ground or other material inr said space.

The wall plate 13 on the bracket arm 12 is provided on its front facewith a horizontal rib 40, best shown in Fig. 1%, the verticalface on thefront of which rib is adapted to support the receiving cup 31, while anupwardly projecting lug 29 receives and support-s an outwardly anddownwardly projecting flange 30 on the rim of the said cylindricalreceiving cup 31, the general conformation of which cup is indicated bythe broken line in Fig. 1%. The said cup 31 is preferably made of sheetmetal and is provided at its rim with an outwardly and downwardlyextended flange 30 for hooking upon the lug 29 on the wall plate 12, atany desired point in the circumference of the said cup. The lower edgeof the flange 80 may bear on the upper face of the horizontal rib 40while the body of the cup just under the iange bears upon the verticalPatented Au. 31, 1909.

face of the horizontally extended rib 40. l

The cup is further supported by a projection 32 on the face of the wallplate.

The cylindrical lower end 16 of the hopper 14 is made a good lit for thecylindrical lneck 15 formed by the two semi-cylindrical upper ends ofthe wall part 10 and front 11 of the casing so as to be adapted to holdsaid upper ends rigidly together when mounted thereon. In order toinsure said cylindrical lower end 16 of the hopper 14 remaining inposition and to form a positive locking together of t-he same and thesaid upper ends a suitable separate clamp ring 33 having a set screw 34,is provided, the inside diameter of which ring is made to fit theoutside diameter of the said cylindrical lower end 16 of the hopper 14.The said clamp ring 38 is first placed on the outer side of thecylindrical lower end 16 of the hopper after which the said lower endwith the ring on it is placed on the cylindrical neck of the two partsof the case and all secured against accidental displacement bytightening up the set screw 34.

The body of the hopper 14 is provided with a window consisting' of apane 3G of glass or other suitable material, let into and substantiallyfitting a window boss or frame 37 in the ,side wall of the hopper andheld in place by six integral lugs 38, shown in development in Fig. 7.These lugs as first blanked out extend inwardly from the edge of themetal of the boss 37 into the space of the window opening'. Said lugs 38are first bent back on the metal that surrounds the inner edge of thesaid boss 37, with the ends 39 of the said lugs projecting into theinterior of the hopper. The pane 3G may be placed in position in saidboss 37 with its front 'face bearing against the rear faces of said bentback lugs 38, as shown in Fig. S, after which the projecting ends 39 arebent down over against the inner face of. the pane 36, for holding thesame in position, as shown in the completed window in Fig. 9.

I claim as my invention:

1. In a coffee or spice mill, having a downwardly and backwardlyprojecting supporting arm provided at its lower end with a wall plate,a'receiving cup supporting lug projecting upwardly on the front of saidwall plate and adapted to receive an outwardly and downwardly extendingflange' on the rim of a receiving cup.

In a coffee or spice mill, a wall plate by which the mill may be securedin place, a horizontally extended rib on the front face of the saidplate, said rib having a substan-4 case having' a cylindrical neckformed by the upper ends of its two parts, a hopper havin@ a cylindricallower end of a size to receive into it the said cylindrical neck, aclamp ring adapted to fit over and inclose the said cylindrical lowerend of the hopper and means for securing the said clamp ring in place onthe said cylindrical lower end and neck of the case.

4. In a coii'ee or spice mill, a two part case 'having a cylindricalneck at its upper end, a hopper having a cylindrical lower endinteriorly fitted to the exterior of the said neck, a clamp ring fittedto the exterior of the said cylindrical lower end and a clamping screwfor binding the said parts t0- gether.

5. In a coffee or spice mill, a sheet metal hopper having a window bossand integral lugs formed on the metal at the inner edge of the openingin the said boss, and a window pane let into the said boss and havingthe ends of the said lugs bent over the outer edges of the said pane onits inner face.

(3. In ay coflee or spice mill, a sheet metal hopper having a windowopening therein with integral lugs at the edges of the said opening, anda window pane covering the said opening and held in place by means ofthe said lugs which are first bent back on the metal surrounding thewindow opening on the onter face of the said pane and then over theedges of the said pane and down upon the inner face thereof.
